Use less energy : Demand-led policy scenarios show promise.

Renew Extra 29th Nov 2025,

Demand-side energy reduction has so far received less policy support than supply-side net-zero technologies, despite the fact that, as this interesting new Nature paper claims, ‘energy demand reductions of ~50% by 2050 compared with today are possible while maintaining essential services and improving quality of life’. That would involve more than just improved technical efficiency of energy use and production, something that is already thankfully underway- although still rather too slowly. It would also mean fundamental changes in how energy is used, with radical reductions in consumption due to new social/behavioural patterns.

The paper notes that ‘policies explicitly targeting large energy demand reductions remain scarce, suggesting that they have so far been disregarded by policymakers owing to real or perceived lack of political feasibility. Instead, national energy strategies frame shifts in demand through an emphatically technological lens, focusing on efficiency gains through electrification and overlooking the broader structural and societal changes necessary to substantially cut the need to use energy..’

To address the perceived ‘persistent gap between academic energy demand scenarios and the scarcity of corresponding energy policy’, in a new approach, academics and policy makers join forces in a demand-focused process of ‘co-created’ UK 2050 energy scenario analysis, led by policymakers and evaluated through public dialogue. It takes more effort, but this paper says the new combined approach is well worth it: the ‘uniquely close involvement’ of policymakers leading the project evidently generated markedly different & positive narratives that reflect policymakers’ concerns while still leading to scenarios with reductions in energy demand of 18–45%, exceeding what policies normally suggest’.

The new paper expands on the method developed by Barrett et al, replacing the ‘academic scenario design’ stage by a policymaker-led process, with input from energy-system modellers. The resultant co-created scenarios are then subject to public discussion, so as to ‘avoid being perceived by policymakers either as ideologically driven or as theoretical academic exercises’……………………………………

The paper also claims that the new approach can deliver practical result and savings: ‘demand-side measures can help reduce societal risks by decreasing future reliance on technologies currently unproven at scale, in the context of a policymaker-led framework……………………………………………………………………………………………………… https://renewextraweekly.blogspot.com/2025/11/use-less-energy-demand-led-policy.html
